Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a polishing device for a mirror surface roller. Background Art

[0002] With the increasing demand for stainless steel in the market, users have higher and higher requirements for important indicators such as the surface finish and corrosion resistance of the strip steel. The existing strip steel is improved by rollers to improve its surface finish, making its surface smooth and mirror-like without scratches. However, in the process of flattening the strip steel, various microscopic defects may exist in the previous process, which may damage the roller surface of the roller; or the roller surface of the roller may also have defects such as grinding wheel marks, which will cause the surface finish of the strip steel to decrease. Therefore, the above situations will affect the production quality and production efficiency of the strip steel.

[0003] In order to solve the above-mentioned problems, there is a Chinese utility model entitled "A polishing device for a rolling mill roll" with patent number CN201822065640.7 (authorization announcement number CN209717345U). The polishing device includes a polishing body, a pair of rolling mill roll lifting devices are arranged inside the polishing body, and a movable lifting polishing device is arranged below the rolling mill roll lifting device. The movable lifting polishing device includes a movable base, a hydraulic lifting rod is arranged on the movable base, and a polishing head is arranged on the hydraulic lifting rod. The polishing head is a replaceable structure, and a guide rail is arranged below the movable base. Therefore, the polishing device of the polishing device can adjust and move itself according to the shape and size of the rolling mill roll to meet the polishing requirements of different rolling mill rolls.

[0004] Although the above-mentioned polishing equipment can adjust the polishing head in multiple dimensions, the roller hoisting device in the polishing equipment cannot be adjusted according to the length of the roller, so the use range of the polishing equipment is limited to a certain extent; since the roller is hoisted and set in the machine body, the stability of the roller is poor. If the polishing equipment is used for a long time, the roller hoisting device is easy to loosen, causing the roller to fall off, which will affect the normal use of the polishing equipment; and the existing polishing equipment has a low degree of intelligence, and most of them require manual operation by workers, which wastes labor costs. For this reason, further improvements need to be made to the polishing equipment for rollers. Summary of the invention
